Bristol Channel members launched their log boats at the OGA55 Rally in Cardiff Bay, July 2018. Will you be bringing your log boat to Cowes?

You will have heard about the Dutch ‘Sailing Clogs’ when granddad’s old wooden clogs were adapted to sail on the canal? Well, the UK OGA has an answer! ‘The Sailing Log’! Well . . . it rhymes! If you have you ever dreamed of making your own sailing Gaffer, but were short on cash or time here is your answer. Take part in the OGA55 Sailing Log Championships to make the fastest and coolest looking Sailing Log!

All the boats shown in the photos here started as logs (or as logs cut down to square section fence posts as found in any local garden centre). These Sailing Logs are based on a simple cut log formula and ‘assembled’ in a couple of hours by family OGA crews using odds and ends found in any boat locker such as gaffer tape, wire, Gorilla glue, plastic bags etc.

Can you do better in the Anniversary year?

Start with a log about 15-20cm diameter, cut to 50cm length. Cut in half to hull shape, add buoyancy to top layer (polyurethane foam works well) and add a weighted keel. Test stability in the bath. Add rudder, mast, bowsprit and sails. Test again in a local pond. Adjust mast position, bowsprit length and sail area to best effect. Varnish, paint and beautify at will. Bring to the OGA55 party on the Solent . Prizes will be awarded for fastest and prettiest.
Above all don’t be shy!

Class Rules

To ensure fair racing ‘Sailing Logs’ must:
1. Be 50cm long (no longer or shorter)
2. Have a gaff rig sail (polythene, cotton or best silk will do nicely)
3. Have a bowsprit

We are looking at good fun here! We want ‘different’ designs and characterful boats that still preform well. We want family participation. There are prizes for the youngest designers.This is an excellent way to find out what makes a sailing boat perform well.

Design Tips

Mast and keel positioning on the hull will be important. If your boat tends to turn up into the wind under sail, move the sails forward by relocating the mast or extending the bowsprit forward. Also try moving the keel backward.

A crude flexible rudder can be made from a flattened drinks can, shaped then inserted in a sawn slot on the transom. 

The main point is to have fun! Don’t be shy, go for it! Are there any Dutchmen attending? They have logs in Holland don’t they?
The Brits challenge you!
